In GSE2 a pause is a macro line that accepts Seconds as the argument. (/click pause x)

in GSE3 make this a block action that allows for the command to accept either a number of clicks or a second value as an arguement.

When it’s a second value this would get converted to a number of clicks in the same manner as the pause is currently calculated (seconds * 1000 / GSE’s options stored MS value).

Either of the following will work:
Wait 3 clicks of the macro

{
    ['Type'] = 'Pause',
    ['Clicks'] = 3
}

Wait 3 seconds (1000MS = 1 Second) this will still depend on GSEOptions.msClickRate

{
    ['Type'] = 'Pause',
    ['MS'] = 3000
}

Wait GCD this will still depend on GSEOptions.msClickRate

{
    ['Type'] = 'Pause',
    ['MS'] = "GCD"
}
